Yesterday I shot at an indoor range in Greenfield. I have not shot a lot of indoor ranges but the ones that I have seemed like the ventilation systems "pushed" fresh or clean air into my back and downrange. Although this place was very busy it seemed like there was no air movement at all. I did inquire and the worker told me that it is running as normal. I was at one end, and the smoke and junk in the air was so thick, that looking to the other end was blurry and very thick. I was shooting at a small bullseye target where the black was about a three inch circle and it was very difficult to see that target at the farthest point from the smoke. Against my better judgement, I stayed for nearly the entire hour and should not have. My clothes were filthy, all cases, ammo boxes and equipment had a gray/black soot on them and the thick black saliva that I coughed up when I left looked terrible. This cannot possibly be a safe environment! This is something that will "turn off" a new shooter very quickly as they might think all shooting is like this experience. I just want to know is the majority of indoor ranges are like this or is there a known ventilation problem at this range?
